MACH-'INE Foa CUTTING PRINTERS TYPES.

Specification forming part ol' Letters Patent No. 43,649, dated July '26, 1864.

To all whom 'it may concern Be it known that I, JOHN .los. OH. SMITH,

of the city of Philadelphia, and State of 'Penn- Sylvania, have invented anew land useful Mafl chine for Cutting PriI1ting-Type; and I do hereby declare that the following is Ia full,"

type heads being separated from each. other by intervening spaces suiiicient to allow a saw to be passed between them without injuring their faces. The making of snch'strips l have described in an application for Letters latent, which application bca-rs even date herewith. My Inaehine will -also cut a number of type at one operation, and of such per-- t'ection that no additional work is required for finishing them.

This machine operates soInewh-.It on thesame principle as that for which l obtained Letters Patent of the United States on the thday of February, 1861.; but. it is improved so as to cut lfrom tiftecnto twentyl type, atevery cut;

andiurther, so that it keeps thc cut type vset up, ready for packing,

To enable others skilled in the art to make and use' my invention, l will proceed to" describe. its construction and mode of operation.

The carriage or sliding table A' moves in two dovetail slides, B. "To .this -table or carria gemost of the mechanism of the machine is attached. C isa circular saw on its mandrel, the'be'aring's of which ,are iixed tothe table D. llnstead of being' arranged as described, the saw might be made movablein sliding guides I Aand the table stationary. Eis a channel in -depth equal tothe type-body. This channel is formed bythe ytwo .guide-bars F and G, of

which theb'ar G is movable. Into this chan -pins inserted through slots in the bar El into* the bar G. The hook I is placed in the spaces between the type-heads by means of the lever J, (which lever is connected with the sliding bar by fa. pivot and small rod, K,) thus enabling the operator to move the` strips together forvward in the channel, so as to bring them into right position for cutting. As soon as the stripsare moved so far' forward as ,te bring the aforesaid intervening spaces (through which the saw has tofpass) in a line square with the cut L in the' sliding table a small bar, N, moving in the box M', (and which bar .Nserves as a gage,) is pushed through the spaces so far that it enters the cut L in bar F,

and by so doing brings the type heads and strips into the required accurate position for being cut. Furthermore, this gage will bring the 'types which are cut oii' from the strip to the outside of the gage N, so that they'stand upright andV enter the channel O. This arrangement of the gage also enables the machine to cut the letters of the alphabet, which are of varying size, in alphabetical rotation,

vso that lone strip may contain all the letters of the alphabet. As soon as this last-mentioned operation is completed the gripping-jaw P, moving in the boi; M, is pressed against the trips by means ot'` thev lever 1t, so as to keep the strips firmly together in accurate position while the sawis operating. The gage-bar N is then Withdrawn and the sliding table moved against thc saw to cut the type oft'. The type which are cut oli' are kept in standing position in the channel O by means of the` movable block S. As soon as the strips are again moved forward in position to be cut they will press the type `already cut off against' the block S, thus preventing their falling down.

The block S'will yield to the pressure of ther vstrips and' move to t-he right for a distance equal to the thickness ofthe type wh-ichare next to be cut off. full of cuttype, they are pushed out into a typegalley and are ready for packing up, thus saving all the labor of setting up the type for packing, which has been hitherto always re.v

quired-s l Having thus described my invention, what I claim, and desire. lto secure` by Letters Patent, is

1. The carriageA and saw B, arranged and .operated substantially as above described,

When the channel O is whereby.' the type-strips can be approximated to and removed from the saw at each successive cut. l

2. The. grippingizmir l), to be operated by hand .for holding the type securely-.in place during theoperation of"cutt.ing, fin the munner described.

3. The movable gage-bar N, for. adjusting type ot' any size toV the cutting-apparatus by gag'ing the type between the heads before they are cnn from the strip. A

4. The channel O and the sliding-block S, for

receiving and supporting the type lef'ter they 1re cut o`,so that; tlliey can'be renioved vwhile.

set up in a composed condition.

5. The hooked feeding-bar H, arranged and operating, as described, for the purpose of feeding a series of strips of type `to the cutter and at the same time holding them down to the surface of the carriage, so as to secure e square cut. V
